IMPROVEMENT IN BOAT-DETACHIN G APPAATUS.

The Schedule referred to in these Letters Patent and making part o! the same.

scription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

This invention relates to a new and useful improvement in a device or apparatus for simultaneously detaching the ends of a boat'from the davit-tackle, and

It consists in operating a detaching-lever hook at the bow and at the stern of a boat by means of a lever and connecting-rods, as hereinafter more fully described.

TheI accompanying drawing represents a vertical longitudinal section of a boat provided with my detaching apparatus.

Similar letters of reference indicate corresponding parts.

. A and B represent blocks of wood or metal permanently attached to the bow and stern on the inside of the boat, as seen in the drawing. These blocks may each be made in two pieces, securedtoget-her by bolts or screws, or of a single piece mortised out or formed with suitable cavities for receiving the detaching-hooks and giving them the necessary play. l

C represents the detachinghooks,` which work as levers, with their fulcrums at D in the blocks A B.

El represents vertical slots in the blocks A B, which allow the hooks F of the davit-tackle to descend suihciently to receive the detaching-hooks, as seen iu the drawing.

G is a lever whose fulcrum is at H, at or near the center or middle of the boat.

I and J are rods which connect this lever with the lower ends of the detaching-lever hooks, as seen at K K.

These rods are connected with the lever G at equal distances on eachside of the fulcrunr H.

As seen in the drawing, the boat is attached to the davit-tackle. By raising the lever G to an upright position, it will be seen that theA detaching-hooks C C will be simultaneously withdrawn from the davithooks. This releases both ends of the Aboat at lthe same instant, thereby allowing the boat to stike the water in its proper position, thusl avoiding the accidents which so frequently occur in launching boats at sea or on the water. l

By this arrangement the boat is dropped squarely into `the water by a simple movement'of the lever G, and by one man. This is a very cheap and simple apparatus, and its advantages must be obvious to all'.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The lever-hooks C C, blocks A B, rods I J, and lever G, when the same are constructed, combined, and arranged to operate substantially as and for the purposes hcrein shown and described.
